There is pressure involved with 'Hello!': Nagarjuna

The promotional video involving all the big stars is very nice.
Ya. The idea was to begin it with NTR gaaru saying the word 'Hello' and end it with Nanna garu saying the same word. But we couldn't find late NTR's video on time. So, Tarak was approached. Since he is a good friend of Akhil, it was great.
